'Righteous Man' in the Bible

And when a righteous man doth turn from his righteousness, and do what is wrong, and I lay a stumbling-block before him, he shall die; because thou hast not given him warning, he shall die in his sin, and his righteous acts which he hath done shall not be remembered; but his blood will I require at thy hand.

And if thou warn the righteous man, that the righteous sin not, and he doth not sin, he shall certainly live, for he hath taken warning; and thou hast delivered thy soul.
